UNITED STATES 1,579,590 PATENT OFFICE.

CHESTER H. BEACH, OF RACINE, 'W'ISCONSIN, ASSIGNOB TO WISCONSIN ELECTRIC COMPANY, A CORPORATION OF WISCONSIN.

DRINK MIXER.

Application filed February 19, 1928. Serial No. 618,825.

To all whom it may concern.

Be it known that I, CHESTER H. BEACH, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, have invented certain new and useful Improvements in Drink Mixers, of which the followin is a specification.

My invention re ates to im rovements in drink mixers, such, for examp e, as are used on soda fountains.

One of the objects of the invention is to provide an electrically driven drink mixer in which the current is switched on by mechanism actuated by the glass or shaker when it is laced on the supporting stand, and is switc ed 011' when the receptacle is lifted therefrom.

Another object is to provide an appliance of this character in which the receptacle is firmly held in position while the motor is running.

A further object is to provide a device of this character which is convenient to operate, and which may be kept in clean, sanitary condition without special efioi't.

In the accompanying drawings I have illustrated one embodiment of the invention.

Figure 1 is an elevation of the drink mixer;

Fig. 2 is a partial sectional elevation on the line 2-2 of Fig. 1; and

Fig. 3 is an elevation, partly in section, of the switch-actuating mechanism.

The device comprises a suitable base 1, supporting a vertical standard 2. The base has a plurality of legs which support the standardin elevated position, with sufiicient space beneath to readily clean the slab or table on which the legs rest. At the upper end of the standard is a housing 3, in which is mounted a switch 4, having an actuating stem 5. This switch may be of any uitable construction, and is preferably a switch of standard form now on the market. It is actuated by a lever 65, in the form of a rod or wire, which is pivotally mounted on a small shaft 7 with its upper end passing through a hole in said stem. The lower end 8 of the lever is bent so as to engage the inner rim of the glass or shaker and be actuated thereby, as hereinafter described. .A coiled spring 9 surrounds the shaft 7, one of its ends 10 hearing against an adjacent part of the housing 4, the other end 11 the ing the same in the full line position shown in Fig. 3, in which position the circuit is open. When said lever is moved to dotted position the circuit is closed. An electric motor 12 is secured to the switch housing 4, by means of a pair of extensions 13 and by screws or other fastening means 14. The agitator rod 15 depends from the armature shaft, and has an agitator 16 at the lower end thereof.

A pair of guide rods 17 ass through openings in a pair of small rackets 18 projectin from the switch housing, and have their ower ends secured to a ledge or supporting plate 19, the latter being clamped etween the base and the standard. The projecting end of this ledge serves as a support for the glass or whatever other receptacle may contain the liquid to be mixed. The guide rods 17 are inclined slightly, as shown in Fig. 1. In placing the tumbler on the supporting ledge 19, the upper rim thereof is slid upwardly along said guide rods until the base of the tumbler is high enough to be moved inwardly against said guide rods and to rest on said ledge. During this upward movement the bent lower end 8 of the pivoted lever is received within the tumbler, the continued upward movement forcing said lower end to the right from the position shown in Fig. 3, against the action of the spring 10. This actuates the switch, turning on the current and starting the motor. The spring-pressed lever 8 also serves to hold the glass firmly against the guide rods 17, thereby preventing it from slipping 011' its support 19. The receptacle is removed by first pulling it slightly away from the standard 2 to slip its lower end ofi its supporting ledge, after which it is lowered, thereby permitting the lever 8 to spring back to initial position, opening the circuit, and stop ing the motor.

The d vioe is readily operated by one hand, as will be seen, as it is necessary simply to place the glass on the support and remove it in order to efi'ect the operation of the device. Obviously, glasses of different heights may be used.

I claim 1. A drink mixer comprising a standard, a motor supported thereby, an agitator rod depending from said motor, a SW1l'.Ch also carried by said standard, a horizontal support for a receptacle, aguide to be engaged by the side of said receptacle when raised onto said support, a pivoted member depending into said receptacle and moved thereby as said receptacle is being lifted to its position on said support, and connections between said member and said switch, whereby the latter is actuated by the positioning or withdrawal of said receptacle on the supporting standard.

2. In a drink mixer, a supporting led e, a pair of inclined rods extending upwar ly therefrom in nearly vertical position, and a rod extending downwardly between said first-mentioned rods and arranged to engage the inside of a receptacle to hold the latter against said first-mentioned rods and prevent it from slipping from said ledge when raised thereon.

3. In a drink mixer, a supporting ledge for a receptacle, a nearly vertical guide member extending upwardly therefrom, a pivoted arm arran ed above said ledge, said arm having a ortion sufficiently above said ledge to exceed the height of any receptacle to be used therewith, the lower end thereof projecting downwardly enough to be received within the shortest receptacle to be used therewith, a switch controlled by the said member, and a motor for stirring the contents of said receptacle and having a circuit controlled by said switch.

4. A drink mixer comprising a base, a standard thereon a switch at the upper end of said standar a bracket adjacent said switch, an electric motor supported by said bracket, a vertical agitator stem depending from said motor, a narrow ledge carried by said base beneath the end of said agitator and to one side thereof, inclined guide members extending from said ledge to said bracket, a switch-actuating arm pivoted on said bracket, one end engaging said switch andvthe other end pro'ecting downwardly into the space occupie by a receptacle to be suplported on sand ledge, and a 5 ring norma y im lling said member in a irection to hold said rece tacle against said guide members and to iiold said switch in position to maintain the motor circuit 0 n.

In testimony whereof, I have subscribed my name CHESTER H. BEACH.

by the side of said receptacle when raised onto said support, a pivoted member depending into said receptacle and moved thereby as said receptacle is being lifted to its position on said support, and connections between said member and said switch, whereby the latter is actuated by the positioning or withdrawal of said receptacle on the supporting standard.

2. In a drink mixer, a supporting led e, a pair of inclined rods extending upwar ly therefrom in nearly vertical position, and a rod extending downwardly between said first-mentioned rods and arranged to engage the inside of a receptacle to hold the latter against said first-mentioned rods and prevent it from slipping from said ledge when raised thereon.

3. In a drink mixer, a supporting ledge for a receptacle, a nearly vertical guide member extending upwardly therefrom, a pivoted arm arranged above said ledge, said arm having a portion sufficiently above said ledge to exceed the height of any receptacle to be used therewith, the lower end thereof projecting downwardly enough to be received within the shortest receptacle to be used therewith, a switch controlled by the said member, and a motor for stirring the contents of said receptacle and having a circuit controlled by said switch.

4. A drink mixer comprising a base, a standard thereon a switch at the upper end of said standar a bracket adjacent said switch, an electric motor supported by said bracket, 9. vertical agitator stem depending from said motor, a narrow ledge carried by said base beneath the end of said agitator and to one side thereof, inclined guide members extending from said ledge to said bracket, a switch-actuating arm pivoted on said bracket, one end engaging said switch and the other end projecting downwardly into the space occupied by a receptacle to be sup orted on said ledge, and a spring normal y im elling said member in a direction to hold said rece tacle against said guide members and to old said switch in position to maintain the motor circuit open.

In testimony whereof, I have subscribed my name CHESTER H. BEACH.
